TLP708 photocoupler
Toshiba Electronics Europe (TEE) has launched the TLP708, an ultra-compact, high-speed inverter-type photocoupler suitable for home appliances, induction heating equipment and factory automation.
The photocoupler features extended temperature performance while complying with the reinforced isolation class requirements of international safety standards.
Performance is guaranteed at temperatures from -40C to 125C.
Comprising a GaAlAs LED that is optically coupled to an integrated, high-gain, high-speed photodetector, the TLP708 is supplied in a six-pin SDIP (shrink DIP) package requiring just half the board mounting area of an equivalent eight-pin DIP device.
Despite its small size, the photocoupler has a minimum isolation voltage rating of 5,000Vrms.
Toshiba's new photocoupler operates with a maximum switching time of just 75ns, allowing it to support typical data-transfer rates of 15Mbit/s.
The integrated photodetector has an open-collector output stage and an internal Faraday shield that provides a guaranteed common-mode transient immunity of +/-15kV/us.
The TLP708 has dimensions of just 9.7 x 4.6 x 4.0mm.
Toshiba also offers a version with extended creepage and clearance distances, which has a board mounting footprint of 11.7 x 4.6mm.
